Château de Boulogne-la-Grasse
Highlight • Castle
For 25 years, he put all his energy and his fortune into creating his 'Great Work', a philosopher's residence, a castle of Mysteries which unfortunately was largely destroyed during the Battle of Matz in 1918.
For his fellow citizens, Count Charles de Boulogne was the builder of a spooky residence. An incomprehensible man, a little crazy, an “enlightened person”?
And yet the sentence he had engraved on the portal gives us the key:
“Sortis patiens esto nulli clauderis honesto”
("Be patient, nothing is closed to an honest man")
